I haven't heard of that yet. Where did you find the article? The Combi is a Swiss Transfer Ticket that includes a Swiss Half Fare Card, but that is discontinued already, as well as the same thing for the Swiss Travel Pass Flex.

Looks like it is true, thanks for the update! I will adapt our Swiss Transfer Ticket page accordingly. I'm not surprised about this. Is hasn't exactly been the most popular ticket because it was the best/cheapest option in only very few cases. The Combi variant apparently still was a tailor made option for some travel agencies, but it has already been discontinued as a mainstream product.

This discount is not a new thing, every year there is a 7% discount on the Transfer ticket usually from about July till about September, not valid if you buy it at sbb itself, you need to buy it by STC
